Intermittent fasting is a hotly debated topic. Some athletes embrace it as part of their training. Others say that by not eating in the morning, you’ll feel more focused as your body isn’t spending energy digesting a heavy breakfast. On the other hand, there are experts who say that intermittent fasting is overhyped and dangerous.
The concept is relatively simple. The most common approach discards the old adage “breakfast is the most important meal” by completely skipping it.
